I just got a letter of Re-assessment from CRA with repayment and penalties in excess of $1500!!! After investigating it was this problem: where I downloaded all T4 and T4A from CRA. Turbotax accepted them but one T4A with Box 48. Of course, I trusted TurboTax to ensure I was filling all the boxes needed, especially for capturing all income source. Lo and behold it did not flag I had to choose the Source for Box 48. Not even a Warning before submission. Therefore this T4A did not appear on the T1 General at all! I spoke with TurboTax and tried to get a 100% Accuracy Guarantee but they said it was my fault. Then why do I need a TAx software if it is not going to help me pick up on these things. TurboTax refused the claim.
Unfortunately, I will not be using TurboTax going forward after 20+ years.
